Quake Watch 2011

As usual Vedur.is is reporting a different size quake but it hasn´t been confirmed yet.
Will be fun to see if it´s downgraded like they usually do.

No scientific data from USGS yet. The EMSC scientific data is in and I would guess from a visual appraisal that that lot averages to around 4.6/4.7

It is always possible if Vedur are using ML that there could be this difference.

Edit: Which, I forgot to say, is what EMSC have it at.

What a great thread! Should be required study (not just reading but actively trying to *gasp* learn) for anyone before making any kind of earthquake thread.
Luckily, it made it to the top of the "recents", or I wouldn't have found it.
Earthquakes are cool, but living where I do (NE Indiana) we only get temblors so small you only feel them if you are standing and paying attention. I did notice one, though. We were at the library, and I started feeling nauseated, like sea-sick. I sat down in the reading area with couches and a really high ceiling, and only got relief putting my head back. Then the earth, and all the glass and tie wires above me started to shake. And my nausea went away. I want to experience another one to see if I can feel it "early" again. (Cue the theme to "Twilight Zone).
The Paranoid Doomers are making it hard to discuss anything anymore! Especially when they "think" they know what thery are talking about and try to link absolutely everything they are paranoid about into one grand unified theory. Oy.

Yes
en.wikipedia.org...

For New Zealand so far in 2011 to end 27th January UTC
there have been;

100 quakes from 1.0 to 1.999ML
521 quakes from 2.005 to 2.99ML
211 quakes from 3.003 to 3.99ML
25 quakes 4.007 to 4.816ML
5 quakes from 5.056 to 5.93ML
and 35 quakes of undetermined magnitude

compared to 2010 same period;

334 quakes from 1.012 to1.999ML
950 quakes from 2.002 to 2.999ML
264 quakes from to 3.977ML
18 quakes from 4.028 to 4.654ML
3 quakes from 5.078 to 5.748ML
and 55 quakes of undetermined magnitude

sure enough the 2011 data for the last 2 weeks will get revised and updated and there will likely be more 1's and 2's added and maybe even a few 3's from offshore that they missed, but generally the stronger quakes are UP in numbers.

Just thought you should know .

Bit quiet here, right now, data for the 28th UTC slow coming in, last quake was at 1500hrs 28th UTC according to Geonet

There is the Wikipedia 'article' if you can call it that, and a Facebook page (!) for the hotspot that says exactly the same as Wikipedia. Any other references, of which there are few, relate back to Wikipedia, the origins of which are obscure. There appears to be no scientific content anywhere that confirms this as a hotspot.

Closest I can find is a 'leaky' transform zone. Do you have any further information?

reply to post by PuterMan


I found this site that refers to the yan mayen hotspot and the other is a pdf file that refers to hotspots around the world. Don´t have time to read them atm , but from skimming through em i think these are what you are referring to.

Yan mayen

Pdf

Seems the my first link was concluded from a study on this site

Looks so much more impressive on this! SHW.UW..EHZ.2011.029

Hmmm the Helen opens one eye
Could this be an awakening?

Is mount St Helens capable of going off like before, or have we seen its worst already.

Its just something ive wondered about.

From my layman's opinion,
I would say anything could happen,.
But I haven't seen any activity there for quite some time,.

reply to post by Catch_a_Fire


It is of course capable as it is an active volcano. It probably has not quite filled the tank however after its last efforts.

Here is the spectrum with reference to the two quakes noted above and the seismogram I posted



This is the sound file

Do not turn the sound up

Mount St Helens sound snippet

The first quake comes at around 30 seconds but it is local so it is very sharp. The space before it is very quiet. Turning up the volume could damage your equipment. Wearing earphones could seriously damage your hearing permanently.

reply to post by Lil Drummerboy


Yes I meant to say on the last post, there is absolutely no indication of any HT in the 8 hours section that I downloaded so I would agree with you there.

reply to post by PuterMan


Sorry should of been a little clearer in that question, i meant could it go off like before so soon after its last big one, but you already answered it in your reply.

I assumed it would need a lot of time to rejuvenate itself, at least to build up the pressure to be capable of another biggy, i just wasnt sure.

Thanks

For some reason your latest link on Mt. St. Helens does not load, anyone else having problems with that link. It just says "Waiting for video".

reply to post by nonnez


I have put the file up on 4shared

Edit: Have to go off line - Chassis fan problems.

Thanks for all the great links - amazing to hear St. Helens growl - she can go back to sleep now.
